Orlando Bloom and Katy Perry’s split has turned ugly just months after their breakup, with very public salvos being fired from both sides.

In the latest round, the Lord of the Rings heartthrob, 48, was photographed at a Halloween costume party with his arm around his rumored new squeeze, actress Rachel Lynn Matthews, 32.

Adding insult to injury, Rachel was dressed as Katy in a black wig and blue flight jumpsuit that resembled the one the pop princess wore on her much-maligned Blue Origin space flight in April.

The Happy Death Day star also recreated the photo of Katy kissing the ground after she returned to Earth.

As readers know, ex-fiancés Katy and Orlando confirmed their split in July after eight years together. They share a daughter, Daisy, 5.

Since their breakup, the “Firework” singer, 41, has been pursuing a headline-making relationship with former Canadian Prime Minister Justin Trudeau, 53.

“Orlando’s been cringing over Katy’s very public romance with Justin,” says a source. “So he jumped at the opportunity to show her he has happily moved on, too. Not only do they share Daisy, but he’s been very careful to only be respectful to Katy, while she’s flaunted her new affair and blasted him with her music.”

In her new song “Bandaids”, Katy seems to hint at the reasons behind the split, implying Orlando had checked out of their relationship.
